Building a deck 12'x16' ground level attached to my house do I need footing?
Generally speaking, no. Although in some locations, if it is attached to the building, it may require a footing. I would suggest you contact your local home depot or other retailer and ask them as they should be aware of local codes. Another option is not to attach the deck and just have it free standing, then deck block should be fine.
You will need to have concrete column using a sonotube and it all depends on exact sizes and your municipality code to determine the diameter of the concrete sonotube depth should be four feet below frost. I recommend you contact a local trusted Pro contractor in your area for specific details and costs.
Depends on what province. But most areas allow just a patio block and a concrete 4x4 post foot. All city websites usually have information and building permit regulations to follow to pass inspection/ pass code. And it has plenty of stability.
All decks no matter the height should have the right type of footing, all depends on the ground type. Cement deck blocks should be banned, I see many decks (10-20) each year sink because of those blocks. Screw piles are the way to go...
Any company that states words for work like should/maybe/probably/etc are not professionals in a certain field of work....
In most locations you can attach a deck to a house without footings. Min. 3" of packed stone , patio stones and deck blocks, BUT if attaching to the house you MUST elongate your bolt holes that are attaching to the house, and the bolts cannot be super tight. They must be able to move if the deck should move.
Talk to your local building inspector when you apply for your permit.
